See which of your friends are already using BBM and quickly send a PIN invite
BBM is introducing a new feature today that makes it easier to find your friends on the service. Just like you'll often find on social networking and messaging apps, BBM can now look through your phone's contact listings to see which of those people are already using BBM but aren't yet able to chat with you.
You'll then have the option to selectively — or completely — send out PIN invitations to those friends and get the conversation going on BBM. Naturally, if one of your friends isn't using BBM you have a quick way to send them an email or SMS invite to download the app as well.
It's a simple setting that's usually part of the setup process on similar messaging apps, and one that can definitely help adoption of BBM if you realize that more of your friends are on it.
